and kept in continual combustion and afford an ample smudge for as long as the apparatus is provided with fuel.

ln the drawings,

F ig. l is a vertical sectional view of the apparatus; l

ig. 2 is a plan; Fig. 3 is Fig. l; and

Fig. 4: illustrates a detail.

ln the example illustrated and specifically described herein the apparatus is `formed principally of sheet-iron.

a is a low cylindrical shell or wall vwhich affords the base of the apparatus and may for that purpose have its lower edge wired, as shown. It has a horizontal wall b secured thereto at a suitable elevation above said lower or wired edge. On `this wall may be placed or secured, centrally thereof, an upstanding element c'whose basal part is preferably cylindrical and whose upper portion is conical; this element, as will appear, is not indispensable. y ment vc if present, affords a fuel support.

Upstanding from and suitably secured at its base to the fuel support (specifically, to wall b) in surrounding and spaced relation to element c and within and spaced from wall a is an outer cylindrical shell d, which may have its upper edge wired. lnto the upper wired edge of shell Z is removably fitted the outer down-turned edge portion e2 of the horizontal flange or laterally projecting wall e at the upper end of an inner cylindrical shell e, which is thus supported at its upper end and projects down into shell Z and is spaced all around therefrom, asat f. g designated handles on wall e whereby the structure e-e-`e2 maybe lifted from the shell. d; Shell e is open at top andvbottoin and forms thefuel hopper. Shell d forms the draft flue 7", `and for the admission of the a sectional view on line Q Wall b, together with eledraft it has openings L in its basal portion; the draft outlet is formed by openings t' in wall e. rlhe draft inlet and outlet openings it and z' are preferably arranged equidistantly around the central vertical axis of the apparatus. The hopper formed by shell e `may be prolonged upwardly to increase its capacity by a cylindrical shell y' which has `an external bead j near one end that is adapted on telescoping the shell j into shell e to abut the latter as a stop; when not in use shell 7' may be 'inverted and telescoped into shell eso as to be almost completely housed therein.

The basal portion of shell al is surrounded by a rotary sleeve damper lo having ports kf to be 'moved into or out of-registry with the draft'inlet openings z to regulate the draft;

[c2 is the handle of this damper.

Z is a series of four angular ears arranged on shell Z 90O apart and all projecting to the same level above the top of said shell'so jas to support a cooking vessel or the like m ,and leave an out-let for draft; two ofthese may have the bail n ed thereto.

The openings 0 in the wall a allow free circulation of air under the wall b, so that the basal part of the apparatus cannot become so heated as possibly to'burn the surface or set lre to any inflammable material on which it is placed.

The youtlet afforded at the lower end of the hopper is spaced from and of less area than the fuel support, over which it is arranged; in consequence of which saw-dust or other` suitable comminuted fuel A placed in the hopper so as more or less to fill the same forms on the support in a pile A sloping' (in the exampleshown, in allfdirections) from said outlet; thus the outlying `portion of the pile underlies the flue f. Further, shell Z being lateral of and `close to the pile (in the example actually 4supporting it laterally) the draft inlet means it stands lateral of and close to the pile. It is not easy to burn comminuted fuel, like saw-dust, slowly, so as to produce a smudge rather than a blaze, and also `keep it burning tuninterruptedly. But I find it entirely possible with my apparatus to do this because, though the part of the fuel body which is undergoing burning is in the form of a pile or mass A', the air is admitted directly to it, a good draft being afforded by the flue f, and as fastlas the maof the apparatus pivotterial in the pile is consumed more falls from the, hopper by gravity/to take its place. In practice, the admission of air tends to form burnt-away vents in the pile, as indicated at A2 iY Fig. '1f Since the fuel burns in a pile or smudge is produced; the quantity of thiscan be regulated by manipulating the damper Ic. The wall d is made to] support the pile laterallybyV so proportioning its diameter with 'reference to .the spacing of the outlet of the hopper from the wall Z) (whieh rep-resents the base of the pile)l that the pile or pyramid A cannot spread to 'the extent it wouldV otherwise assume. This makes it possiblefor the draft inlet openings 7i to be arranged so that the fuel pile will tend to cover them,` whereby combustion proceeds effectively Vin the immediate vicinity of each inlet; this is an important factor in keeping the fuel burning uninterruptedly. The" element c is not indispensable, as stated-without it a natural cone would be formed lby the fuel itself down whose slope the' fuel to replenish that consumed would be precipitated; but it is found an advantage to ,provi-de' element c, since the fall of vfthe fuel takes place more readily down its smoothslope than' it does down the slope of such Va. natural cone.

From time to, time the ashes which accumulate in the well formed at p may be dislodged therefrom through the draft inlet openings h into the exterior hearth well q by taking the apparatus by the bail n and rolling it on its lower edge.

The apparatus may be utilized as a stove, for cooking and the like,"by removing the structure e-G--e2, in which case of course other fuel than `saw-dust would be used.
